Description

The refinishing process of furniture and timber for recycling and the mixed abrasives for the process}

The present invention relates to a technique for surface re-treatment for recycling furniture and wood and the use of the mixed wear material 34 used for surface treatment, in particular, by using a combination of hard wear and mixed wear in combination with all kinds of furniture. And surface reprocessing of wood. The surface treatment of conventional furniture and wood is almost cut with a saw, or a costly labor-intensive work method using a sanding grinder or sand paper (FIG. 1) is used to obtain a uniform and clean surface during the surface treatment of furniture. Due to the large amount of time and manpower, regeneration after surface reprocessing is avoided.

The purpose of the present invention is that the amount of waste wood generated is 1.117 million ㎥ annually, which is 1.2 times the total domestic consumption of wood and 9 times the domestic production, but the recycling of wood is about 30%, and the furniture is far less than that. Timber and wood that must be implemented to solve problems such as resource depletion due to excessive use of timber, economic burden due to imports, costs for the disposal of furniture and various pollutants (dioxine, etc.) that occur during disposal (incineration). It is intended to provide an economical, quick and environmentally friendly way to recycle furniture.

According to the present invention, the constitution of the mixed wear material for the surface treatment of wood and furniture and the degree of contamination of the wood or furniture (1) to be treated by a method of treating the mixed wear material by spraying (36) simultaneously with the compressed air (6), The pressure of the compressed air is adjusted (8) according to the coating material, the thickness of the coating surface, the hardness of each wood, etc., and the hard wear material 24 and the mixed wear material 34 mixed with the soft and hard wear material are each wear material container. The mixed abrasive material, which is dropped from the mixed abrasive material container 10 and the hard abrasive material that is dropped from the hard abrasive material container 12, and the compressed air are mixed and sprayed through the air hose 26 to the injection nozzle 28. A method is provided.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a method used for the surface treatment of conventional furniture, the type and shape of the furniture is a variety of sand paper (2) by hand to process the bent and uneven parts and the flat part using a sanding grinder (4) Remove paint and dirt. In addition, belt type sand grinders are used for the surface treatment of large wood and plywood, but they are rarely used for the surface treatment for recycling.

Figure 2 shows a method of surface treatment of furniture and wood using a mixed wear material 34 and a hard wear material 24 according to the present invention, the compressed air (6) is a control valve with an air pressure gauge ( 8) to adjust the air pressure. As there are various types of furniture and wood, various coating materials are used for furniture coating, and the thickness of the coating varies depending on the application. If the painted surface is thick and hard as in the conventional Homica furniture (polyester-based paint), the hard wear material 24 is used to remove the painted surface and the old time after the primary removal treatment so that the wood is not damaged using the mixed wear material 34. Second surface treatment. Solid wood furniture with a painted surface (lacquer, polyurethane, etc.) is removed only with the mixed wear material 34. In the case of wood, in consideration of hardness, contamination, etc. of wood, the hard wear material 24 and the mixed wear material 34 are used in combination. For this reason, the silo wear container uses one mixed and one hard wear container. The mixed abrasive 34 is introduced into the silo-type mixed abrasive container 10 through the upper inlet 14, and the discharge amount is controlled by the control valve 18. Compressed air and mixed wear material is injected into the nozzle 28 through the high pressure hose (26). The hard wear material is introduced into the silo-type hard wear material container 12 through the upper inlet 16 and the discharge amount is controlled by the control valve 20. Compressed air and hard wear material are injected into the nozzle 28 through the high pressure hose (26). Considering the type and characteristics of the existing coating material of the furniture (1) to be reprocessed, the thickness of the painted surface, and the hardness of the wood and wood of the furniture (1) to be reprocessed, the hard wear material (24) and the mixed wear material ( 34), it is possible to use irrespective of the type of wood, the type and thickness of the coating material by controlling the injection amount of each abrasive and the pressure of the compressed air (8), and the shape and internal diameter of the nozzle 28 are small. Since the nozzle 30 and the nozzle 32 having a large inner diameter can be selected and used, the nozzle 30 can be freely applied regardless of the shape or size of the furniture.

3 is a cross-sectional view of the container according to the present invention, the silo-type mixed wear container 10 has a soft wear material (24)-in the soft wear material 22-walnut shell powder, corn flour, plastic media, sawdust, etc. Aluminum oxide, silicon carbide gold steel, sea sand, glass beads, etc. are mixed and poured into the inlet 14 and mixed with the compressed air through the outlet 40, the discharge amount can be adjusted by the valve (18). The silo type hard wear container 12 may also be used in the same manner as the mixed wear material container, but the outlet 42 of the hard wear material container is made smaller so that the amount of the hard wear material is easily controlled so that the wood is damaged. The amount of discharge can be adjusted by the valve (20).

4 illustrates the use of a nozzle 30 having a small inner diameter and a nozzle 32 having a large inner diameter when spraying a wear material according to the present invention to treat surfaces of furniture 1 of many types and sizes. In order to maximize the efficiency of the work together with the selection of wear materials and air pressure control shown in FIG. 2, the selection of the inner diameter of the nozzle suitable for the work is very important. In the case of FIG. In this case, the nozzle 30 having a small inner diameter is used, and the furniture having a large processing surface as in the case of (B) can increase the speed and efficiency of work by using the nozzle 32 having a large inner diameter.

Such a surface treatment apparatus can be conveniently and widely used for surface treatment of all furniture and woods as described above with high economy and speed.

As described above, the treatment of the surface of furniture and wood for recycling using the present invention is much more economical than the surface treatment method of furniture, which relies on the existing manual surface treatment method and recycles almost all furniture and wood. Can be applied for If the surface treatment is done by the existing method, the recycling cost is close to the purchase cost of the new furniture in some cases, thus avoiding the recycling. It can be easily peeled off due to unstable coating surface, and it can solve all problems caused by the large amount of deadly pollutant during disposal by incineration, which greatly improves the recycling rate of furniture and wood, reducing the damage of forest and various costs for disposal. It can provide the surface treatment technology of furniture and wood which can reduce the burden.
